Silt and Debris Management Program

Our Silt and Debris Management Program runs in all areas of greater Sydney.

Our projects are currently underway and will continue until mid 2018.

About our Silt and Debris Management Program

We're removing silt, sand and sediment from our wastewater and stormwater pipes, as well as from open channels, rivers and creeks.

This work improves our systems and protects public health and the environment.
Depending on the type of work being done, the timing of the work will vary.

We first write to affected customers about the work.

Where the work will have a higher impact, we may also door knock affected customers to discuss the work and impacts in detail.

How will you be affected by this work?

If we're working in your street, you'll notice an increase in noise, truck and vehicle movements. This happens while we access maintenance holes connected to our pipes or when we access stormwater channels, creeks and rivers.

As most maintenance holes are in the road, there will be some temporary traffic changes during the work. 
 

Why does the work need to be done at night?

If the pipes are under busy roads, road managers such as the Roads and Maritime Services and local councils may only permit us to work at night. This helps to prevent disruption to traffic during the day.

We often have to work at night to clean wastewater pipes, as this is when flows in the pipes are at their lowest.
 

How long will the work take?

This often depends on how easily we can access the maintenance holes and open channels, and how much silt and debris needs to be removed. Some work may take as little as a few days, while other work can take several months.

For the longer projects, it's unlikely that the work will be in front of your property for the whole time. We'll move from one maintenance hole to the other along the length of the pipe or along the length of the open channel.

If work is happening in your street, we'll advise you about the work in advance.
